Answer:

r=3

y=3x

Step-by-step explanation:

We are given that a graph.

The graph shows  a proportional relationship between x and y.

From given graph  we can see that when x increases then y is also increases.

Therefore, y\propto x

y=rx

Where r=proportionality constant

x=5 and y=15

Substitute the values then we get

15=r(5)

r=\frac{15}{5}=3

Substitute the value of r

Then, the equation to represent the relationship is given by

y=3x

The constant of proportionality (r) appears to be 3.

y = 3x . . . . . . . x = number of tickets sold; y = dollars collected

Answer:

\boxed{f(6) = 34}

Step-by-step explanation:

Composition of functions occurs when we have two functions normally written similar or exactly like f(x) & g(x) - you can have any coefficients to the (x), but the most commonly seen are f(x) and g(x). They are written as either f(g(x)) or (f o g)(x). Because our composition is written as (f \circ g)(2), we are replacing the x values in the g(x) function with 2 and simplifying the expression.

g(2) = 3(2)

g(2) = 6

Now, because we are composing the functions, this value we have solved for now replaces the x-values in the f(x) function. So, f(x) becomes f(6), and we use the same manner as above to simplify.

f(6) = (6)^2-2

f(6) = 36-2

f(6) = 34

Therefore, when we compose the functions, our final answer is \bold{f(6) = 34}.

Which is the correct formula to find the distance between two points (a, b) and (c, d)?
stepan [7]

Answer:

Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points. Created by Sal Khan and CK-12 Foundation.

Does ANYONE know?????
daser333 [38]

Answer:

150 votes were casted

Step-by-step explanation:

So first, we know that Amy received 48 votes. Then Neil received 1/4 as many votes as Amy. So we can divide 48 by 4:

48/4=12

Neil got 12 votes. We also know that Neil and Amy's votes together is only 40% of the votes casted in total. So we can add their votes together and then find a fifth of the votes casted by dividing the 40% in half:

12+48=60

60/2=30

So now 30 votes are 20% of the total votes casted, now we just have to multiply by 5:

30*5=150

150 votes were casted
